Heat treatment process of AISI 420c stainless steel ball

- Jan 15, 2019-

AISI 420c is a martensitic stainless steel with certain wear resistance, corrosion resistance and high hardness.Therefore, the AISI 420c stainless steel ball also has such characteristics.For stainless steel balls, the heat treatment process is different for different materials.

The purpose of heat treatment of martensitic stainless steel balls such as AISI 420c stainless steel balls is to increase the hardness, thereby enhancing the wear resistance of the stainless steel balls and prolonging the life of the workpiece.

These stainless steel balls are high-carbon and high-chromium. These two elements are a contradiction. Because the carbon content and chromium content are too high, it is easy to cause uneven distribution of chromium, which affects the anti-rust performance of stainless steel.

Normally, the heat treatment temperature of the AISI 420c stainless steel ball is about 2-5MM1050 degrees.

After the production and processing, the AISI 420c stainless steel ball also needs automatic cleaning, automatic appearance inspection, automatic rust prevention, and counting packaging, which are the key factors affecting the quality of the steel ball.

The appearance inspection of AISI 420c stainless steel ball is an indispensable process in the processing of steel balls.

The appearance inspection of steel balls mainly includes the detection of surface scratches, rust, surface spots and the like.
